Abstract

Following a discussion on WW-boson mass observed at the CDF and ATLAS, we explore the parameter space allowed in the 2HDM+SS model. Further, the model parameter space is constrained through vector-like leptons via muon g2g-2 measurements. We show our results for additional scalar mass fixed to mS95m_S \approx 95 and 150150~GeV keeping the standard Higgs-boson mass at 125~GeV in all four types of 2HDM+SS model. The chosen mass of the singlet scalar is motivated by the excesses seen at the CMS and ATLAS data in proton-proton collisions at the Large Hadron Collider.
